STAMFORD — Robbers posing as residents on Connecticut Avenue appear to be using a similar tactic against food deliverymen.

Police said at least one man approaches a Chinese food delivery driver outside an apartment where he is attempting a delivery, shows him a weapon and tries to steal money and food.

It happened twice in the past week.

The latest incident was Tuesday, when a driver from a Richmond Hill Avenue restaurant was walking toward an apartment about 8 p.m. and a man waved at him from the side of the building, Sgt. Robert Shawinsky said.

When the victim approached the man, he noticed the suspect was masked and holding what looked like two handguns, Shawinsky said. The driver told police he panicked and ran back to his car.

Police said the victim reported hearing a soft popping sound as he ran from the scene, but he was not struck or injured. Officers later found a couple of steel balls from a BB gun in the area.

In last week’s incident, two men walked to the victim and pointed a gun at him while he was attempting a delivery, according to the report. Police said those men stole cash, a cellphone and food from the driver.

No suspects in either incident have been arrested.

Capt. Richard Conklin said police are investigating both cases and have yet to determine if they’re connected.

”We are aware that there have been two similar such incidents in just a matter of days,” he said. “We are responding to that.”

There have been at least a dozen robberies or attempted robberies of Stamford food delivery drivers in the past six years. About half of them involved Chinese food drivers and most of the incident happened on the West Side.

In January, a Chinese food deliveryman was held up at gunpoint on the South End. A suspect in that case was arrested a week later and his case is still pending in court.

The suspect in Tuesday’s attempted robbery was described as 6-feet tall with a medium build. He was wearing a red mask and a black hoodie.
